Las Vegas firefighters are calling a homeless man a hero for saving two small children from a fire, reports the AP. Fire officials say a 3-year-old girl and a 10-month-old boy were trapped in a burning apartment Friday morning after the children's grandfather was cooking food and the stove caught fire. The grandfather escaped from a back bedroom but couldn't get to the children. A Las Vegas Fire and Rescue rep says that's when 36-year-old Anival Angulo happened by and pried open a screen door. The man pulled both children out of the home, and they were treated at a hospital for smoke inhalation. (More Las Vegas stories.)
